extracting saves from emu nand to actual nand

So I set up my Wii following the guides here to run everything off my USB drive and it's pretty full.

Anyway I can not get Zelda Skyward sword to run from USB and have given up trying.....it sorta works but randomly freezes at a black screen making it unplayable. I want to continue playing this game now but my save file only exists on my NAND backup....

I want to go ahead and play this one game from my actual retail copy, but even when I run it from that with a USB loader it freezes. So it seems to me my only choice is to run it from the regular disc channel but I can not seem to figure out how I can get my save file from the emunand so that I won't have to start over.

I was trying to run save game manager but I can't figure out how to get it to work....it runs but then fails when I try to do anything with it.
